Abstract

A circuit breaker contact assembly includes a line conductor having a folded back fixed contact end, a fixed contact mounted on the contact end, and a movable contact arm having an inner edge and first and second ends. A movable contact is mounted on the first end. The movable contact arm is pivotable about the second end between a closed position in which the inner edge extends adjacent the contact end with the movable contact in contact with the fixed contact to form a reverse current loop, and an open position in which the movable contact is pivoted away from the fixed contact. The contact arm includes a first inner longitudinal member extending along the inner edge and a second outer longitudinal member. The first inner longitudinal member has a higher electrical conductivity than the second outer longitudinal member, which has a higher shear strength and a lower specific density.
